A new two-mode thermo-and squeezing-mixed optical field

We propose a new two-mode thermo-and squeezing-mixed optical field, described by the new density operator ρ=(1–e^f–|g|²) e^ga†b†e^fa†a|0>_bb < 0|e^g*ab, where|0>_bb < 0|is the b-mode vacuum, e^fa†a represents the thermo-field, and e^ga†b indicates squeezing. The photon statistics for ρ is studied by virtue of the method of integration within ordered product (IWOP) of operators. Such a field can be generated when a two-mode squeezed state passes through a one-mode dissipation channel.
